A former worker from a Melbourne Jewish college has been sentenced to eight years in prison for a string of sexual offences.

David Samuel Cyprys, 45, who worked in various roles at the Yeshiva College, admitted to interfering with nine children at the school in offences dating back to the 1980s.

Though several of the offences were committed while Cyprys was a minor himself, his offending continued until his 20s.

He was convicted in August of five counts of rape and pleaded guilty to additional charges including indecent assault and gross indecency.

Cyprus will serve a minimum term of five-and-a-half years before he is eligible for parole.

He will also be put in the sex offenders register.

The Yeshiva college has been widely criticised for not acting earlier on complaints against Cyprys.

Manny Waks, who campaigns against child sex abuse, said outside the court that he will take civil action against the college after being given court approval to publicly declare that he was one of Cyprys' victims.

You have no doubt been hearing a lot about the Paris Agreement and know that it pertains to climate change, but are too embarrassed at this stage to ask for an overall explanation of what it's all about.
